IMPLEMENT FOR FINISHING AND PUDDLING CONCRETE.

Specification of Letters Patent.

Patented Nov. 30, 1915.

Application filed March 29, 1912. Serial No. 687,106.

To all whom it may concern:

Be it known that I, ARTHUR B. DODGE, a citizen of the United States,residing at Cambridge, county of Middlesex, State of Massachusetts, haveinvented an Improvement in Implements for Finishing and PuddlingConcrete, of which the following description, in connection with theaccompanying drawing, is a specification, like charactors on the drawingrepresenting like parts.

his invention has for its object to provide a novel implement adaptedfor use in concrete work for giving a smooth finish to coneretebeams,posts, or other structures, and which is also of use in puddlingconcrete and preventing the formation of; voids therein.

The features wherein my invention resides will first be described andthen pointed out in the appended claim.

Referring to the-drawings wherein I have shown some embodiments ofmyinvention,

Figure 1 is a view of an implement made in the form of a fork andembodying the invention; Fig. 2 shows how the'device is 1 used; Figs. 3and 4 show different embodiments of the invention.

In Fig. 2 I have shown at la form for molding a. concrete structure, and2 represents the concrete therein. Concrete as used in buildingoperations is formed by mixing broken stone and sandwith somecementitious substance and when the concrete is poured some of thebroken stone will naturally occupy a position against the form and willconsequently be visible when the form is removed. In many cases aconcrete structure with a smooth surface is desirable, and to supplythis end, it has been the common practice heretofore to insert anordinary spade or shovel intothe form close to the wall thereof, andwork said spade up and down thereby to force the stones and coarseingredients of the cement away from the wall so as to allow the fineringredients to fill the space'olose to the wall.

The object of my'invention 1s to provide In Figs. 1 and 2 I have shownan implement comprising the handle 3 of any suit-.

able construction provided at one end with a head 4 to which a pluralityof tines'5 are secured. Each tine is provided with a plurality ofprojections 51 which extend therefrom at different angles and the tinesare connected by one or more bars or webs 8. The tines may either bemade integral with the head 4: orremovable therefrom. InFigs.

1 and-2 I have shown a construction in.

which the tines are removable from the head, while in Fig. 3 I haveshown a construction in which' the tines are integral with the head. Inthe construction shown in Figs. 1 and 2 each tine has a neck 6 at oneend which extends through an aperture in the head' i, each neck having anut 7 applied thereto by which it' is firmly but detachably held in'position. This implement is used as shown in Fig. 2, that is, byinserting it in the mass of concrete 2 directly against the wall of theform 1, and then working said device up and down in the concrete therebyto force the coarse material away from the wall and allow the fineringredients of concrete to '(JOl'XlOlIltO position against thewall.

In Fig. -l I have shown an embodiment of my inventionwhereinthe deviceis provided with a plurality of rows of'tinos. In this device the head49 which is secured to the handle 3 is wide enough to receive two rowsof tines 5'. A device having this construction is useful. in assistingto force the concrete into different parts of a concrete mold so as toprevent the formation of voids in the. concrete. My invention,therefore, is useful not only for giving a smooth finish to the exteriorsurface of the concrete struc- Q menses I claim as new and desire tosecure by Letters Patent is In a device of the ciass described, thecombination with a handle having a head, of a plurality of fingersextending from said 10 head and each having projections extendingtherefrom at difierent angles, and a bar connecting said fingers neartheir lower end.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing Witnesses.

ARTHUR B. DODGE.
